Development of interlocking flyash brick machine and study of brick structural efficiency

Abstract

Eco friendly manner fly ash management and utilization is the need of the hour and one of the possible ways of using it is by fabrication of interlocking bricks out of it. This research focus on the development of interlocking brick machine and bricks manufactured is tested for dimension stability, water absorption, compressibility strength and efflorescence test. The machine setup was successfully fabricated and used for production of interlocking flyash bricks. The setup mainly consists of machine structure, hydraulic system and pan mixer. Two varieties of interlocking bricks were produced with the size of 12” × 6” × 5” and 12” × 8” × 5”. Based on the results of the test the interlocking bricks are found suitable for better replacement of the ordinary bricks.
